Moon has decided not to visit Japan for the Tokyo Summer Olympics, citing a failure to set up a summit with Japan's prime minister that would produce meaningful results in improving relations. The signs on a banner at left read "Expel Hirohisa Soma, deputy chief of mission at the Japanese Embassy in Seoul, from South Korea." (AP Photo/Ahn Young-joon)
